'acquiesce' originates from Latin, specifically the word 'acquiescere,' where 'ad-' meant 'to' and 'quiescere' meant 'to rest.'

'acquiescere' transformed into the Old French word 'acquiescer,' and eventually became the modern English word 'acquiesce' through Middle English.

Initially, it meant 'to find rest or peace in something,' but over time it evolved into its current meaning of 'to accept something reluctantly but without protest.'
